Ford Powerstroke 6.7L - Transmission Tune (2020-2022)
Type: Tuning Software
Upgrade your transmission to match your power mods.
This Transmission Control Module (TCM) tune is designed to enhance drivability and durability by optimizing your Ford Powerstroke’s shift logic, torque converter lockup, and line pressure. Specifically tuned for trucks running emissions-delete setups or increased engine output, this tune ensures your transmission can handle the demands of added power.
When tuning your 2020–2022 Ford 6.7L Powerstroke for more horsepower, the factory transmission calibration becomes a limiting factor. This TCM tune eliminates soft shifting and delay-prone factory behavior by improving shift speed, torque converter engagement, and line pressure. The result is a firmer, smarter, more responsive drivetrain ready for heavy-duty towing or performance use.
